April 30, 1940. R; E. REEDER FEATHERWEIGHT RESPIRATOR Filed Jan. 17. 1939 Rose Feeder Mmmm Patented Ap 30, 1940 UNITED STATES PATENT OFFICE FEATHERWEIGHT RESPIRATOB Rose E. Reeder, Ravenna, Nebr. Application January 1'7, 1939, Serial No. 251,431

1 Claim. (01. 128 -146) This invention relates to means for filtering the air entering the nose and mouth of a person so as to prevent foreign matter and germs from entering said parts, the general object of the invention being to provide a frame for holding filtering material over the nose and mouth of a person with means for holding the device in place;

The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is a view showing the device in use as covering the nose and mouth of a person.

Fig. 2 is a vertical sectional view through the device and showing how it covers the mouth and nose of a person.

Fig. 3-is a view of the frame,

Fig. 4 is a transverse sectional view of the device.

In this drawing, the numeral l indicates a substantially U-shaped wire frame, the bight I of which is substantially of arcuate shape and the limbs I" of which slightly converge from the bight. The extremity of each limb is rolled, as shown at 2 and an intermediate part of each limb is looped to form an eye 3, said eyes extending in an opposite direction from the bight, which extends forwardly. Porous material 4, of suitable cloth or the like, is looped about the frame so as to provide an elongated filter member of double thickness, as shown, the curved bight of the frame tending to make the cloth assume a shape of substantially U shape in cross section. The edges of the cloth are suitably connected together.

Thus when the device is pressed against the face, with the bight extending around the chin 5 and the limbs extending upwardly along the cheeks, one on each side of the nose, the filter material will cover the mouth and nose and thus filter the air entering such parts.

The device is held in place by a string 5, which 10 may be of elastic material, which has hooks 6 at its ends for engaging the eyes 3, the string passing around the head of the user and over the ears, as shown in Fig. 1.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent,

It is to be understood that changes may be made in the construction, combination and arrangement of the several parts, provided such changes fall within the scope of the appended claim.

What I claim and desire to protect by Letters Patent is:

A respirator including a metallic frame formed 25 from a single length of wire having a central arcuate portion adapted to fit around a wearer's chin and a pair of side portions extending from the ends of the arcuate portion in a plane at right angles to the plane of the arcuate portion, 30

said side portions converging upwardly and having adjacent their mid-lengths rearwardly extending eyes; a doubled fabric 'cover fitted over said frame with the eyes projecting rearwardly of its side edges, and an elastic head band having its ends connected to said first mentioned eyes with at least one connection constituting a hook for ready disengagement of the head band end.
